I'm just curious if the MAC address of the laptop NIC ever gets past my
home broadband router.

Assuming my home broadband router is set up with the typical defaults,
is there any way that the laptop's wlan0 or eth0 MAC address can get
past the router to an assailant?

I realize at a wireless hotspot, where I don't control the router, the
MAC address can be logged - but does a typical home broadband router
setup prevent an intruder from obtaining the laptop NIC MAC address?

Your IPV6 address can be derived from whatever you want it to be derived
from and your MAC address can be whatever you want it to be.

Your browser itself sends out enough info to
pretty much individually ID you. (I'd bet you
thought the browser only told the web server
what brand, so to speak, it was and your
computer operating system. Hah!)

Every time I try it using the same Firefox browser several of the
numbers change. First I was "only one in 2,721,631 browsers have the
same fingerprint as yours", on the next try I was "unique among the
5,443,259 tested so far". Either I've got a good sneaky browser or the
website is a scam. I'm betting on the second.

Your browser fingerprint appears to be unique among the 5,443,287
tested so far.

Currently, we estimate that your browser has a fingerprint that
conveys at least 22.38 bits of identifying information.

Safari on same machine, a minute later:

- lots and lots of info, with numerous differences
between the two browsers.

I have 11 bits (one in 2600 tested), but I forge my headers
and do not allow scripting or flash.
Can't make it less than that.
The site is legit. Latest versions of Chrome and Firefox can
ID you no matter what you do, so I use an old version (of Firefox)
